Resveratrol analogues attenuate oxidative stress after renal I/R. Kidney tissues of the vehicle-, RSVA405- and RSVA314-treated rats were collected 24 h after reperfusion for determination of (A) inducible nitric oxide synthase (iNOS) and (B) nitrotyrosine protein expression levels by Western blotting. Data are presented as mean ± standard error (n=3–5/group). *P < 0.05 vs. control; #P < 0.05 vs. vehicle. Con, control; Veh, vehicle; R405, RSVA405; and R314, RSVA314.
